Question
may i continue to drive my truck with a knock sensor code. I live 200 miles from my dealer.

Answer
Hi Jerry,

I would be concerned about the code for a couple of reasons. Your engine is not running to maximum efficientcy and the concern you could be doing damage to you aluminum engine.

You don't have to go to a dealer to get it repaired. If you have a decent service garage closer, I am sure they can fix it.

I understand you dilema. I lived 100 miles away from the closest dealer and I only had to drive 45 miles for a decent repair shop.

Try to get this handled as quickly as you can so you don't end up forced to the dealer for major repairs. For now, you should be running premium anyway, but if there is a parts store around you, pick up and install octain additive into the tank.

Good luck!

Alarm system questions cannot be answered on this forum. These systems are not what I can answer. Without being physically at the vehicle and not knowing what kind of electrical service has been done on the vehicle, there is no possible way to give an accurate answer over the internet. My expertise is in Ignition/key based anti-theft systems. These issues include GM VATS (resistor chip in key blade) PASSLOCK (MRD)-ignition lock rotation based, no special ignition key and the PKIII Transponder (computer chip in key) systems. These systems are not alarm based and are integral with the starting of the engine. This is why I cannot diagnose alarm problems without physically looking at the vehicle: Alarm systems are a completely different annimal than ignition key/lock based anti-theft system. Many alarm questions come from vehicles 10 years old, and since older, many hands that had been involved over the years.I am an expert in all GM factory (ignition/key based)systems. Alarm system questions pose to many situations beyond my knowledge as to what has been done to the vehicle over the years. Some guy may have actually wired the stereo into the alarm system. Who knows? Over my past 30 years in vehicle wiring repair, I have seen unbelievable wiring disaters done by guys that consider themselves "mechanics." I have seen stereos and alarms intalled using surgical tape. I have seen modules burn up, un-fused circuits, wiring jambed between the doors and even lamp cord used for a starter kill. To answer alarm questions over the internet without examining the vehicle is like asking; What does it take to remove a dent?
